Classified under industry code SF, this bushing features an inside diameter of 0.189 inches (wire size 12) with a tight tolerance of +0.0001 to +0.0004 inches to ensure accurate hole location and repeatable drilling results. The body outside diameter measures 0.3125 inches (5\/16 inch) with a length under head of 5\/16 inch. Constructed from steel with a head type profile, it is compatible with the LS-1 lock screw and is designed as a renewable bushing, allowing it to be replaced without replacing the liner bushing. Machinists, toolmakers, and fixture builders are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe SF205FU is used in drill jig setups across manufacturing, metalworking, and precision machining environments. Its slip-fixed design allows the bushing to be inserted into a liner bushing and locked in place during the drilling operation, making it well suited for single-operation drilling where the bushing remains fixed throughout the cut. The head style provides a positive stop against the jig plate surface, maintaining consistent positioning across repeated production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed (SF) bushing type for single-operation drill guidance\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.189 inches with precision tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production jig environments\u003c\/li\u003e\n  \u003cli\u003eHead type design provides positive stop against jig plate surface\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows replacement without disturbing the liner bushing\u003c\/li\u003e\n  \u003cli\u003eLS-1 lock screw compatible for secure retention during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an SF-type slip-fixed renewable drill bushing compatible with LS-1 lock screws and standard liner bushings accepting a 5\/16 inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists during jig setup.
